Installation warnings

Colibri®

- Recommended mounting position: vertical

- Installation must comply with local standards and legislation

- Before working on the electrical connections, disconnect the device from the main power supply

- Before carrying out any maintenance operations on the device, disconnect all electrical connections

- For safety reasons the appliance must be ﬁtted inside an electrical panel with no live parts accessible

- Do not expose the device to continuous water sprays or to a relative humidity greater than 90%

- Avoid exposure to corrosive or pollutant gases, natural elements, environments where explosives or mixes of ﬂammable gases are present, dust, strong vibrations or shock, large and rapid ﬂuctuations in ambient temperature that might cause condensation in combination with high humidity, strong magnetic and/or radio interference (e.g. transmitting antennae).

- When connecting loads be aware of the maximum current for each relay and connector

- Use cable ends suitable for the corresponding connectors. After tightening connector screws, tug the cables gently to check their tightness.

- Use appropriate data communication cables. Refer to the EIM data sheet for the kind of cable to be used and setup recommendations.

- Minimize the length of probe and digital input cables as much as possible, and avoid spiral routes around power devices. Separate from inductive loads and power cables to avoid possible electromagnetic noises.

- Avoid touching or nearly touching the electronic components ﬁtted on the board to avoid electrostatic discharges.

Quick guide for parameter selection

A. Setting controller in Superheat control mode.

Make sure that r12 = 0 (OFF) and change the settings. The setting will depends on the system requirement.

Enabling Regulation control ON / Oﬀ switch (optional)

HwMainSwitch = 1 (default is 0, i.e S4 sensor). For standalone conﬁguration it is recommended to enable Regulation control ON / Oﬀ switch in order to control start/stop regulation when needed, otherwise the controller will start regulating when controller is powered up.

Select Refrigerant

o30 = 1 – 49

Select valve setting

For EIM 365, ﬁrst select Proper Danfoss valve t ype (PNU 3002). For EIM 316/336, the default valve type is ETS 6. n37 = 384 x 10 micro step (3840 micro steps = 480 half steps) n38 = Max. steps / sec

Deﬁne pressure sensor range in bar absolute (x10)

o20 = Min. Transducer pressure o21 = Max. Transducer pressure

Deﬁne min/max superheat

Deﬁne SH control type: SH Mode : 1 = MSS , 2= LoadAP (PNU 3026 ) n10 = min. superheat reference n09 = max. superheat reference For ﬁxed superheat deﬁne n09 = n10

Deﬁne MOP (optional)

For EIM 365, Startup mode P-control has been enabled as default. for detail check startup mode parameter (PNU 64322).

To start the superheat control

Set r12= ON

B. Setting controller in valve driver mo de using MODBUS signal

Make sure that r12 = 0 (OFF) and change the settings so they ﬁt to their application:

Select Application mode

o18 (PNU 2075 )= 1 i.e Manual control

Select valve setting (optional)

For EIM 365, ﬁrst select Proper Danfoss valve t ype (PNU 3002). For EIM 316/336, the default valve type is ETS 6. n37 = 384 x 10 micro step (3840 micro steps = 480 half steps). n38 = Max steps / sec

Select manual opening degree

o45 Manual OD % (PNU 2064) 0 = fully closed, 100 = fully open

By changing parameter o45 Manual OD, the valve will move accordingly regardless of r12 parameter value.
